I need help with my 1999 ML 430...It won't start

Hi Guys,
I'm a new Benz owner, and new to this forum. I have a 99 ML430 which I tried to add an HHO generator to to save some gas $$$... (I'll update you on it as soon as it's installed) but the problem i'm having currently is kinda weird. I think there was a short somewhere in my car not sure where but I know there was one because I did it by accident messing with my wires, anyways the car was fine immediatly after the short but later on that day after driving around for a bit I parked my car to grab groceries came back to it and it wouldn;t start. Tried to crank it and nothing no noise, no turn, no crank nothing all the lights interior, dashboard etc. all working nothing dimming when I try to start. I tried to jump it and nothing, took off the battery connection cleaned the heads and nothing again. One thing changed after I reconeected the battery is a weird clicking sound coming from dashboard...same clicking sound as my turn signal everytime I try to start the car it comes on for 30 seconds...and sometimes it clicks when I bang the steering wheel or dash as well. If it makes a difference the short happened right underneath the steering wheel I accidentally touched a hot wire to a screw underneath the steering wheel area... Anybody have a clue what it could be or how I can go about solving the problem on my own before I spend a tonne of cash with MB dealership.... one mechanic I went to said it's probably my alarm module?? But I read it somehwere that the alarm module would let the car start and then shut off right away i'm not getting a sound or anything from the car while trying to start it. Any help would be greatly appreciated.

P.S. I plan on documenting my HHO installation and results and share them with this forum.
